ELECTRIC GAS-LIGHTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 591,071, dated October 5, 1897.

Application filed February 24, 1897. serial No. 624,852. (No model.)

To aZZ whom it may concern.-

Be it known that I, ADRIAN LIVINGSTON BOGART, a citizen of the United States, residing at Jamaica, in the county of Queens,State of New York, have invented a certain new and useful Improvement in Electric Gas-Lighting Apparatus, of which the followingis a specification.

Great difficulty has heretofore been experienced in connection with the ignition of gas in certain situationsas, for instance, in connection with the VVelsbach incandescent lamps, with such lamps as are usually employed in the Pintsch system of illumination, and in connection with other gas-burnin g apparatus, whether for lighting or heating purposes. The difficulty in connection With such burners as the Welsbach arose from the fact that it was desirable, particularly for outdoor illumination, to inclose the burners, whether one or a group, in a suitable chamber, so as to protect the same. l/Vhere the globes were within reach, the operator was obliged to remove the same in order to ignite the gas,or where out of reach the usual method was to keep the gas burning continuously, turned down when not required for illuminating purposes. The latter mode of course which are not inclosed.

I accomplish the principal object of my invention by providing what I term a flashladderthat is, a length of pipe perforated with numerous fine holes and connected through a bypass with the main supply of gas, controlling this by-pass by an automatic spark-producing device, whereby by the op eration of the spark-producer the gas which is automatically turned on to the flash-ladder ignites the same, and whereby the flashladder will be extinguished when it has performed its work of igniting the main gasflame. V

By employing a fiash-ladder of the descrip tion above referred to and a by-pass therefor controlled independently of the main gas supply I am enabled to locate the spark-pic ducing mechanism at a sufficient distance from the gas-consumin g apparatus,where considerable heat is generated, to avoid the dangers incident to the heat thereof.

In the accompanying drawings, forming part of this specification, Figure 1 is an elevation of an inclosed street-lamp embodying my invention. Fig. 2 is a view, partly in section, of the sparloproducing device, the flashladder, and by-pass for controlling the supply of gas thereto, with the electrical connections shown diagrammatically. Fig. 3 shows diagrammatically my invention applied to the ignition of a heating apparatus located within cylinder-rolls.

I will first describe the apparatus shown in detail, as in Fig. 2. In this figure, E E represents a gas-pipe forming the flash-ladder, which is provided with small holes (1 d 61 (Z d d, placed in such juxtaposition to one another and drilled in such direction through the surface of the tube E E that if the gas be turned on to such tube and that issuing from the lowest aperture be ignited by any means the flames will flash or communicate from one to the other. This tube may be of any required length and bent into any desired shape, providing that there be not too much descent from the horizontal at any point along its line. The upper extremity of this flash-ladder E is placed in close proximity to the main gas-jet to be ignited. The lower end of this fiashe ladder is attached to a spark-generating and valve-controlling mechanism, the preferred form of which is shown in the drawings, Fig. 2, and which I will now describe.

A is a metal valve-cylinder having a valveseat F, into which fits, gas-tight, a conical valve G, to which is attached a metal stem I-I, having at its lower end an iron armature J.

Below the valve-cylinder A, but attached to the same, is an iron plate K, which serves as the yoke for the two magnet-spools M l M, I, and K consequently forming a horseshoe electromagnet. This latter is inclosed in a gas-tight metal case D, the lower end of which is provided with a screw-thread and attached to the gas-supply m. \Vhen the valve G is in its normal position, as shown in the drawings, the gas is prevented from entering the flash-ladder E on account of the weight of the stem ll and armature J. It now the electromagnet M I be energized, the armature J will be attracted and lifted as far as the dotted lines, and at the same time, through the agency of the stem II, the valve will be opened to the position shown in the dotted lines and the then will pass, as indicated by the arrows, through the valve-opening into the ilasl1-ladder E, whence it will issue from the various perforations (Z (Z (Z cl.

Above the valve G is located an arm TV, which passes through the side of the valvecylinder at V and extends upward to the point U, where it terminates in a piece of platinum orcother electrical conducting material. This forms one of the electrodes and rests against a second electrode which extends downward to the point S, where it is rigidly attached to but insulated from the valve-cylinder at B. The spring h is fixed to the side of the valve-cylinder, the bent end p of which presses against the vertical portion of the arm \V, causing the two electrodes at U to impinge and the part V to press firmly against the opening in the side of the cylinder-valve. These two latter parts are ground together, so as to act as a valve and valveseat, permitting no gas to issue from the point V.

Q is an ordinary galavanic battery; X, a primary spark-coil, such as is used in electric gas-lighting, and 'l a common press-button or circuit-closer.

T, X, and Q, are connected as is customary in the electric gas-lighting art, one pole of the battery being usually in connection with the gaspipe, and from T a wire runs to an insulated binding-post at I), from thence to one of the helices M, then to the other P, and thence to the insulated electrode at S, whence the current would descend through the two electrodes at U to the vertical arm, cylindercasing, and back to the gas-pipe along the metallic parts of the case.

The operation of the parts is as follows: The valve being closed in its normal position, as shown, if the circuit is closed at T the current will pass by the route just given through the two helices M P, energizing them. This would cause the armature J to be attracted, and by means of the valve-stem ll the valve G would be raised from its seat, permitting the gas to how upward through the valve, filling the flash-ladder and issuing outward through the holes therein. The valve G in its upward course strikes against the curved spark-coil X, and gaspipe.

arm lV, raising it, and as, on account of the spring 1), V acts as a pivot or fulcrum the upper end of the arm W will at U be sepa rated from the fixed electrode,'causing the circuit to be broken and a spark to be produced at such break. The armature 'i'alls again a slightdistance, permitting the end of the arm W to descend and bring the two electrodes at U again into contact to be again immediately separated. by the rcenergizin g of the electromagnet iii 1. As a consequence a vibratory movement continues at U as long as the circuit is kept closed at the press-button T in the well-known manner oi. electric bells. The valve G remaining open and the spark continuing to be produced at the point U, the gas which issues from the :ilash-ladder at the lowest opening (Z becomes ignited and the flame climbs from one opening (Z to the next until it has reached the termination oi the tube E. As soon as the pressure is re moved from the push-button T, breaking lhe circuit, the valve falls back into its place, extinguishing all of the flames from the flashladder. It can thus be seen that there is no gas consumed or passing through the flashladder until the circuit is closed, that the valve remains open not only for the length oi time required to lill. the tube of the flash-hut der E and ignite all of the ilames, but that the ilash-ladder flames themselves can be kept burning for a sullieient length of time to insure the ignition of the main ginlame of a burner or heating a 'iparatus that it is de sired to light, after which, by the removal oi the linger from the push-lnitton, all gas and flame is cut oil? from the flash-ladder itsell'.

In Fig. l I have shown the HPpilCfLiLlUll. oi my invention to the ignition of lVelsbach lights in a hanging lantern. In this iigure, 1 represents a closed glass globe; 2, a metallic hood or canopy; 3, a gas-pipe, and +1: a valve controlling the gas-supply. 5 and (J are two \Velsbach incandescent gas-lights or ilrgaml burners. 7 is an automatic sparleproducer and valve-controller, as shown in Fig. 2,with the flash-ladder E rising vertically from 7 and bent in proper i'orm. above the top of the chimneys of the two gas-lights 5 and ti. This flash-ladder is drilled with numerous small holes, as has been before described. 8 8 S is a circuit-wire properly insulated and connected to a binding-post upon the automatic device 7. From thence it is run along the gas-pipe, in sulated and attached by any of the usual methods to the press-lnitton T, battery (3, if the gas now be turned on by the main stopcock 4 it will. iill the pipe 3, descend into the lantern, and emerge from the burners 5 (5, but will be cut oil from the flash-ladder E by means oi the automatic valve-controller 7. By closing the circuit at the button T the gaswayis open to the flash-ladder by means of the automatic device 7, ignited, and after ignition climbs to the top of the flash-ladder, the jets there igniting the main flames of the burners 5 U,

after which, the circuit being broken at T, the flame is extinguished from the flash-ladder E and all useless waste of gas terminated there.

It can be easily understood that my invention is applicable to the ignition not only of two lights, as shown, but of a single one or any number in a group, the only modification being the extension in length of the flashladder. By the arrangement shown in Fig. 1 the automatic valve-controlling and igniting device is located at a point entirely below the main flames of the gas-jets and in a position where it is subjected to the lowest temperature.

Fig. 3 shows the application of the same device to the ignition of a gas heating-burner within a roller, a being the roller, a portion of which is broken away to show the interior. m m is a gas-pipe passing in through one of the trunnions and pierced with holes along the line it n for the purpose of doing the heating on the interior of the roll after ignition. 4- is the main stop-cock controlling the gassupply. 7 is the automatic controller and igniter, with its flash-ladder E provided with proper apertures in its wall to admit of the iiame flashing along its surface from the lowest portion at the automatic device 7. T, X, and Q, constitute the electric circuit, as in the other figures. The gas being turned on at 4 will fill the main supply-pipe m m and issue through the openings of the heating-pipe at n n. The circuit being closed at T will cause the gas-supply to be opened by the automatic device 7 to the flash-ladder E and ignited, when its flame will flash along the surface of the flash-ladder to its extreme end, igniting the main heating-iiames at an, the flash-ladder being extinguished when the circuit is opened at T.

I do not desire to confine myself to the special construction of theautomatic device as shown and described. In the place of performing the operation by means of a single wire and circuit-closer, as shown, two wires may be employed with two sets of magnets within the automatic device, one serving to turn on and ignite the flash-ladder and the other to extinguish the same in the wellknown manner shown and described in Letters Patent No. itl,458, dated November 25, 1890, and No.377,505, dated February '7, 1888, issued to Leroy S. WVhite, or by any of the automatic gas-lighters at present in use, or I may operate the spark-producing device by a pull in the shape of a chain or otherwise, having devised such a mechanism to be shown in an application about to be filed by me, or I may employ instead of av sparking device an incandescent igniter on the plan of the well-known Gardner gas-lighting apparatus,

the main object of my invention being the production of a gas-igniting spark or heating effect at a point where it will be applicable to the lighting of gas passinginto or through a flash-ladder and controlling by the operation of the gas-igniter the valve for turning on and off the gas in a flash-ladder.

I claim ,1. The combination in an electric gas-igniting apparatus, of a main gas-supply pipe, a by-pass, valves for independently controlling the main supply and by-pass, a fiashladder connected to the by-pass, an electric igniter, and means for operating the said igniter and jets to be ignited by the flash-light, substantially as set forth.

4. The combination in an electric gas-igniting apparatus, of a by-pass from the main gas-supply, a flash-ladder connected With said by-pass, and an electrical valve-controller adapted to maintain the valve open while the circuit is closed at the circuit controller or key, and to close the valve when the circuit is open at the circuit controller or key, substantially as set forth.

5. The combination with a closed globe, of a gas burner or burners located therein, a valve or cock controlling the supply of gas thereto, a flash-ladder within said globe, a valve controlling the gas-supply to said flashladder independently of the gas-burner supply, an electric igniting apparatus, and means for operating the same and the valve simultaneously, substantially as set forth.
